[Solved]Anyone know what this could be?

This is the error:

java.lang.ClassNotFoundException: com.Nickname97.bukkit.Pluginname.Pluginname

This is the only plugin I am running.

 

The plugin.yml's 'main' node is incorrect.

 

Ahh, Thank you.

EDIT: Coryf88, When you say that do you mean it should be a different file completely?

 

That error means that it cannot find a class named "Pluginname" in the package "com.Nickname97.bukkit.Pluginname". So, open up your main plugin class (the one that extends JavaPlugin), copy the class name and package, then add the class name onto the end of the package, and update the main node in the plugin.yml file with that.

 

Thanks! I solved it!

 

Just FYI, according to bukkit guidelines you shouldn't have "bukkit" in your package name.

 

Isn't it fine if the second section is not bukkit? i.e. org.bukkit/com.bukkit == BAD and com.sample.bukkit ==GOOD

 

Tell that to Nijikokun. It's Nijikokun's plugin I am updating.

 

You need to append your plugin. yml.
